After a 14-year-old boy aboard a bus was arrested under suspicion of public intoxication, a crowd of people at the conference refused to allow a police cruiser carrying the boy leave, ABC5 reported.

The video's caption reads:

Today after the ending of the convening as everyone was walking down the street CPD arrested a 14 yr old. While everyone was demanding his release an officer pepper sprayed the crowd and further escalated the situation. In unity and solidarity everyone was demanding that he be released, and we stayed and protested until they released him!

Additional video from the protests captures police officers pepper-spraying the crowd in order to disperse it.

“They began to form a barricade around the car urging the police to let the young man go but they wouldn’t, and when they were linking arms and doing chants one of the police officers began pepper spraying the whole line," conference attendee Destinee Henton told Cleveland NBC affiliate WKYC. "They were on the ground covering their faces. He was still spraying them toward the ground so that’s when more people started coming out.”
